INHALER.-

SPECIFICATION iorming part of Letters Patent Il'o. 351,577, datedOctober 26, 1886.

' Application filed June 21, 1926;

Serial No. 205,761. (No model.)

To all whom it may concern.-

Be it known that FRANK A. GHEsEBRo, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Inhalers, of which the following is a specification.

My invention relates to inhalers for inhaling or inwardly applyingmedicated vapors or anaesthetic agents; and has for its object toimprove the construction of such contrivances, whereby they may be mademore convenient in use, their several parts made strong, and easy ofseparation and assemblage, and liability of accidentally mixing the acidwith the alkali or medicated liquid in the use of the device isobviated.

To the foregoing ends my invention consists in the improvements which Iwill now proceed to describe, so that others skilled in the art may beable to make and use the same, reference being had to the accompanyingdrawings, forming a part of this specification, and the invention beingparticularly pointed out in the claim hereto appended.

Of the drawings, Figure 1 represents a perspective View of my inhaler.Fig. 2 repre sents a vertical section thereof.

The same letters of reference indicate the same parts in both figures. I

In the drawings, a represents the main vessel and receptacle for thealkali or medicated liquid.

b represents the stopple for the vessel a, co mposed of any suitablematerial, its upper portion, 0, being preferably formed of hard orvulcanized rubber, and the part inserted in the neck of the vessel of asofter compound.

(1 represents the acid-receptacle extending through and fitting closelyin an aperture formed in the stopple I). Said acid-receptacle isprovided near its upper end with an offset, e, adapted to fit acorresponding offset formed in the stopple,. whereby the acid-receptacleis given a secure seat in the stopple, as is clearly represented in Fig.2.

The acid-receptacle d is provided with a stopple, f, similar incharacter to stoppleb of the main vessel a, and the air-inlet tube 9,formed as a single part or piece and provided with the funnel h, formedas an integral part thereof, for filling the acid-receptacle d withoutdisturbing it or its attached parts, is passed through an aperture inthe stopple f, and preferably extends down nearly to the acid, as shown.Atubegi, preferably construct ed of glass, and as a single piece orpart, is bent into U-form at its upper end, and has its shorter arm, j,extended barely through the longer arm is passed through an aperture inthe stopple Z) of the main vessel a, and extends do'wn into the alkalior liquid anaesthetic agent in the latter vessel.-

, Z- represents the inhaling -tube composed, preferably, of glass, andhaving its end connected with the main receptacle a,which tube is passedthrough the stopple b, so'as to communicate with the interior of thelatter vessel, above the an aesthetic agent therein.

By-con'structing an inhaler as hereinbefore described,and forming andarranging the parts as shown, I am enabled,among other things,as will beunderstood by those skilled in the art, to form the several parts oftherequisite thickness or strength, and thusfavoid liability of breakagein the ordinary use of the contrivance, a difficulty heretoforeexperienced with inhalers of common construction. Again, by constructingeach part as separate from and independent of each and every other part,and arranging them as specified in the claimlhereinafter made, I amenabled to repair such and to easily and readily separate and manipulatethe several parts. Each part is also simple in form and construction,making the device cheap of manufacture. Moreover,it will be seen that inthe ordinary use of my invention liability of mixing the acid withalkali or medicated liquid in the main vessel by tipping the device toone sideis obviated, a matter of importance in contrivances of thischaracter.

I am aware that it is not new to construct for the anaesthetic agent, aninlet-tube, atube or tubes connecting one receptacle with the other, andan inhaling-tube, and Iiltherefore ments, broadly, but limit myself tothe conseveral parts as specified in my claim, wherestopple f of theacid-receptacle (I, while its parts as may accidentally become broken ordamaged at slight cost andwith little trouble,

inhalers with an acid-receptacle, a receptacle struction relationship,and:combination:of the do not claim a device embodying these ele- IOO bythe improved results set forth in the explanation of the constructionand use of the device are accomplished.

What I claim is 5 An inhaler consisting ofthe main vessel or receptacleand its stopple, the acid-receptacle constructed as a single or separatepart, and its stopple, said acid-vessel being extended through andseated in the stopple of the main to vessel or receptacle, the air-inlettube constructed as a separate or single straight stem or pieceextending through the stopple of the acid-receptacle, and provided witha funnel as an integral part thereof at its upper end, the t5conncctingtnbe i, bent into U form at its upper end, andhaving itsshorter stern extended through the stopple of the acid-receptacle andits longer stem passed through the stopplc of the main receptacle andinto the medicated liquid therein, and the inhalingtube having 20 oneend passed through the stopple of the main receptacle, as set forth.

In testimony whereof Ihave signed my name to this specification in thepresence of two subscribing witnesses, this 15th day of June, 1886. 25
